Нашел прикольный скрипт на страницах maillist’ов freebsd

#——————- create jail script ———————–
#!/bin/sh
ID=${ARGV[1]}
DEST=/jails/jail.${ID}
IMAGE=/jails/images/jail.${ID}

# create a blank disk image of 512 Mb
dd if=/dev/zero of=${IMAGE} bs=1024k count=512
mdconfig -a -t vnode -f ${IMAGE} -u ${ID}
bsdlabel -w md${ID} auto
newfs md${ID}c
mount /dev/md${ID}c ${DEST}

# create jail using created image
cd /usr/src
mkdir -p ${DEST}
make world DESTDIR=${DEST}
cd etc
make distribution DESTDIR=${DEST}
mount_devfs devfs ${DEST}/dev
cd ${DEST}
ln -sf dev/null kernel
